Alaska Dept. of Environmental Conservation v. EPA, 540 U.S. 461 (2004), is a US Supreme Court case clarifying the scope of state environmental regulators and the Environmental Protection Agency (EPA). In a 5–4 decision, the Supreme Court found the EPA has authority to overrule state agency decisions under the Clean Air Act that a company is using the "best available controlling technology" to prevent pollution.
